Abstract (en)

Data content is formatted to ensure compliance with a policy when the data content is processed in a processing environment. The data content subject to the policy is obfuscated in a manner such that the processing environment cannot read the data to process it. A key is provided within the policy itself for revealing the data content in the obfuscated content and the policy is attached to the obfuscated content. In this manner, a processing environment that is policy compliant can merely read the policy, identify the key, and extract the data content from the obfuscated data for normal processing. However, a processing environment that is not compliant will not be able to recognize or extract the data content from the obfuscated content and is thus prevented from using the data in a manner that may not be compliant with current policies governing the data. The data content can be a structured document such as XML.
